Abstract

The present study evaluates various reliability measures including transition state probabilities of a sub system on a website which caters to the ‘contact us’ functionality using copula technique. The system in context uses a combination of both frequently asked questions and contact us forms on the website to help customers getting resolutions to their queries. The failure and repair times for the system follow exponential and general distribution respectively. Introducing two different types of repair between adjacent states the system has been studied to evaluate MTTF, steady state probability, availability and cost analysis by using Gumbel-Houggard family of copula.
